man/ms operator loosens the screw Q. and swings that is, the peripleral surface of the wheel poses the wheel rotates in a direction away left so as to discngagethe side P from the turned and with it the driving shaft then shaft D, and the lower end of the rack l? is engaged by a bearing Q} to hold the teeth P in mesh with the gear wheel The gear wheel is engaged on opposite faces by friction disks S, S having notches S of which. the notches S of the disk .3 are engaged by projections E formed on the hub in" of the crank E, and the notches S of the disk S are engaged by lugs formed on the shaft ll Now when the crank is turned the lugs turn the disk S and at the same time the shaft D is rotated its lugs D turn diskS, and as the disks S, S are in frictional contact with the gear wheel they the latter so that the rack l? is caused to move upward a d downward according to the direction in which the crank E is turned at the time. The up and down sliding movement given to the rack P causes the corresponding side l or P to imparta turning motion to the pinion 0, whereby the shaft L is rocked and with it the holder L so as to swing'the razor blade K from one sideof the peripheral face it to the other side thereof.

It is understood that for stropping purfrom' the cutting edge of the blade K, as shown, for instance, in 5, in which the arrows indicates the rotation of the wheel l, it being understood that the crank E is turned for the time being in the inverse direction of the arrow a, and when the motion the crank E is reversed then the holder It. is rocked to swing the razor blade 'K to the other =ide, as indicated in dotted lines in Fig. 5, the wheel I then being rotated in the inverse directio-n of the. arrow a.

Vl hen it is desired to hone the razor, the

the bearing Q, for the rack P over to the pinion O and to engage the side 1 with the oppositeside of the pinion 0. After this has been done the screw Q is screwed up to fasten the bearing Q in place, and when the crank E is now turned to rotate the wheel l in the dire :tion of the arrow a then the cutting edge of the razor blade K is in the position indicated in dotted lines in Fig. 5,

I travels toward the cutting edge of the blade lVhen the motion of the crank E is reversed.

theholdcr ll swings the blade K to the op site side of the wheel l immediately prior to rotating the said wheel in the inverse direction of the arrow it is understood that when the crank E is the arm thereof c ngz'i es one of the pins F or F to rotate the wheel F, but when the crank E is stopped and turned in the opposit-e direction, then the gear wheel F and consequently the wheel ll remain stationary I for the time being, that is, until the arm D engages the other pin F or F to rotate the gear wheel F in the opposite direction and with it the wheel I. During this time that the gear wheels F and I are stationary, a swinging motion is given to the blade holder L, so as to swing the razor blade'K from one side of the wheel 1 to the other side thereof to prevent the cutting edge from cutting into the peripheral surface of the wheel I. It is further understood that the frictional connection between the rack P and the shaft D and crank E imparts'inovement to the rack P for rocking the shaft L and the holder L and for holding the cutting edge and 'blade K with the desired force in frictional contact with the peripheral face of the wheel I. In order to increase or diminish the tension between the disks S, S and the gear wheel it use is made of a wing nut T screwing on the outer threaded end D* of the shaft D and against the crank E so that the hub E of the latte: can be pressed with more or less force in contact with the disk S, to increaseor decrease the friction between the gear wheel R and the disks S, S, of which the latter eiGStS against a shoulder on the shaft D, see Fig. 2. By the arrangement described the sides of the'cutting edge of the razor blade K are nioved'in fllCflC-" ngagement with the peripheral face of the wheel I, which besides a rotary motion has a bodily sliding movement in the direction of its axis to in sure a perfect stropping or honing of the cutting edge.

in order to permit a convenient int-erchange of a stropping wheel and a honing wheel, the wheel I is reinovably held on the bearing J by the use of a catch U pivoted on the flange I of the bushing I? and extending across the portion of the bearing J fitting into the notch 1 Thus by swinging the catch U upward into a vertical position the wheel I can be lifted 0d the sleeve G and another wheel can be substituted and locked in place on returning the catch U after the bearing J is fitted into the notch i The upward sliding movement of the rack P is limited by astop lug P on the ra ck, engaging the bearing Q, and the downward sliding motion of the rack P is limited by its upper portion engaging the pinion O. The blade holder L is removably mounted on the head N and for this purpose the shaft L is provided with an'annular groove L ged by a slide V held adjustably by a screw V on the head N.

Fly the arrangement described holders fordilfei'ent blades can be readily placed in position on the machine. Thus razor blades of ordinary razors, or blades of safety razorsiuay be readily stropped or honed.
